Using Substitution Variables in Templates
Substitution variables are used to set AP-specific values on each AP in the group. It is obviously not desirable to
set the IP address, hostname, and channel to the same values on every AP within a Group. The variables in
Table
92 are substituted with values specified on each access point's APs/Devices > Manage configuration page within
the AirWave User page.
Sometimes, the running-config file on the AP does not include the command for one of these variables because
the value is set to the default. For example, when the “transmission power” is set to maximum (the default), the
line “power local maximum” will not appear in the AP running-config file, although it will appear in the startup-
config file. AirWave would typically detect and flag this variance between the running-config file and startup-
config file as a configuration mismatch. To prevent AirWave from reporting a configuration mismatch between
the desired startup-config file and the running-config file on the AP, AirWave suppresses the lines in the desired
configuration when auditing the AP configuration (similar to the way AirWave suppresses lines enclosed in
parentheses, which is explained below). A list of the default values that causes lines to be suppressed when
reporting configuration mismatches is shown in
Table 92 .
